How it works: Spray adds new dimension to touchscreens: Discover how the University of Bristol's latest innovation can help turn all sorts of 3D surfaces into touchscreens

HEAVILY INSPIRED by graffiti spray art, a team of researchers at the University of Bristol have developed a special spray coat that allows the creation of interactive displays on 3D objects. Eclipsing the appeal of traditional square and rectangular casings, the new technology, called ProtoSpray, makes it possible to ‘spray’ touch-sensitive screens onto objects as complex and irregular as a Möbius strip.
